When using the external repos feature, it is generally best practice to
mirror the external repos you want to use (e.g. with a tool like
repomirror), and use your local mirror url for the external repo in Koji.

Dear Koji Development Team,
I hope this email finds you well. I am writing to seek your expertise
about using QEMU as a Koji Builder to build packages for the aarch64 on the
fedora platform.
When Koji invokes mock for building, it spends *a significant amount of
time updating yum metadata*(≈15mins, <mirrors.kernel.org> set as external
repo) resulting in taking 30 minutes to init buildroot alone (download
speed≈2.8MB/s). I tried to use squid to cache mirror of fedora by modify
/etc/kojid.com: yum_proxy =
http://xxx:3128 but the "--installroot"
process still costs a lot of time.
I would like to know if there is any information that I may have
overlooked or any guidance or recommendations you may have to speed up init
buildroot process on QEMU builder.
Thank you in advance for your time and consideration.
